This invention relates to valves, and more especially to a selfair-escaping and self-starting floating valve.

An object of the invention is to provide a floating member which is ofrelatively larger size than the valve seat opening it is adapted toclose, so that the floating member will have the advantage of being ableto break away existing vacuum when seated to make the valveselfstarting.

Another object of the invention is to provide a valve of this type thatwill permit free flow of liquid through the valve when the line is open,and will automatically close the line in which the valve is installedafter the liquid ceases to flow.

With the above and other objects and advantages in view, the inventionconsists of the novel details of construction, arrangement andcombination of parts more fully hereinafter described, claimed andillustrated in the accompanying drawing in which:

Figure l is an elevational view of an embodiment of the invention;

Figure 2 is a vertical, sectional view on the line 2-2 of Figure 3 andFigure 3 is a top plan view of Figure 1.

Referring more in detail to the drawing, the valve embodying theinvention is generally designated by the reference numeral H).

The valve ||l comprises a tubular valve casing having a closed bottom l2and an open top i3. An annular flange |4 extending at right angles fromthe top of the casing provides a support for the disc-shaped cover |5which, by means of fasteners I6, is removably secured to the flange I4.

Near the bottom of the casing N, there is formed integral with thecasing, a partition H, which divides the casing into the upper or floatchamber I8, and the lower chamber I9. Centrally of the partition thereis provided a tubular member 20, having the conical shaped valve seat20' and the height of the member 20 is greater than the thickness of thepartition Within the chamber 8, there is located the float or valvemember 2|, the circumference of which is much larger than thecircumference of the member 20. The float 2| is provided with a conicalshaped portion 2| centrally of its bottom which is adapted to engage andbe seated in the valve seat 20' when the float 2| moves downwardly inthe casing When the member 2| is in position to have the portion 2|thereof engage the valve seat 20', the height of the member 20 willraise the float above the partition so that the vertical fluid drop 22will form communication with the housing II at 23, slightly below thebottom of the valve 2|. A float level is maintained in the housing bymeans of the vertical fluid arrester 29 and the outlet pipe 24, and thevertical drop 22 and inlet pipe 25. The pipes 24 and 25 extend inopposite directions to each other, but are in the same horizontalplanewith each other.

The drop 22 is connected to the inlet pipe 25 by a coupling 26, and anescape tube 21 forms communication between the housing II and drop 22.

The outlet pipe is connected to a T-coupling 28, which is connected tothe vertical arrester .pipe 29 which, in turn, is connected to theT-coupling 39 which, by means of the pipe 3|, is connected to thehousing to form communication with the chamber l9. A brace rod 32 weldedat 33 at its opposite ends to the pipe 29 and housing braces thearrester pipe 29 to retain it in the normal vertical position. Clean outplugs 34 close the couplings 28 and 30 at their remaining openings.

There has thus been provided a floating valve which is of greatercircumference than its valve seat, thereby having the advantage of beingable to break any vacuum occurring in the valve housing to permit thevalve to open the valve seat.

In operation, the valve I0 is placed in position to prevent air frompassing through the housing H, and valve seat 20 out of the housing intothe outlet pipe 24. Thus a floating basin or chamber I8 is created whichis provided with a constant float level caused by the horizontalalinement of the pipes 24 and 25. This level is maintained by the fluidarrester 29 which causes the liquid to rise against the force of gravityto cause constant back pressure in the chamber l8 and maintain theliquid level.

The air escape pipe 21 being in the same line with pipes 24 and 25permits the air to escape from the chamber |8 out of the pipe 25. Thusany air below the liquid level which would interfere with the operationof the float valve 2| would escape through the pipe 21. The pipes 29 and3| and their manner of communication with the housing permit free flowof the liquid at all times. Should the liquid cease to flow, the floatwill close the seat 20 and prevent air passing through the valve intothe line 24.

It is believed that from the foregoing description, the structure andoperation of the invention will be apparent to those skilled in the art,

and it is to be understood that changes in the 1 minor details ofconstruction, arrangement and combination of parts maybe resorted to,provj vided they fall within the spirit of the invention 1 and the scopeof the appended claim.

Having thus described the invention, what is claimed as new and desiredto be secured by Letters Patent is:

An apparatus of the type described, comprising a valve housing, apartition in said housing dividing said housing into upper and lowerchambers, a float valve in said upper chamber, a valve 4 housing,vertical pipe means connecting said inlet and outlet pipes to the inletand outlet means for said housing, an air escape tube connected to saidhousing and to said inlet pipe in the same horizontal plane therewith.
